    • Causality constraints on corrections to the graviton three-point coupling 

      Otero Camaño, Xián; Edelstein Glaubach, José Daniel; Maldacena, Juan; Zhiboedov, Alexander (Springer, 2016-02-03)
      We consider higher derivative corrections to the graviton three-point coupling within a weakly coupled theory of gravity. Lorentz invariance allows further structures beyond the one present in the Einstein theory. We ...
    • Cavitation effects on the confinement/deconfinement transition 

      Buchel, Alex; Otero Camaño, Xián; Edelstein Glaubach, José Daniel (Elsevier, 2014)
      Cavitation is a process where the viscous terms in a relativistic fluid result in reducing the effective pres-sure, thus facilitating the nucleation of bubbles of a stable phase. The effect is particularly pronounced in ...
    • Compactifications of the Klebanov-Witten CFT and new AdS3 backgrounds 

      Bea Besada, Yago; Edelstein Glaubach, José Daniel; Itsios, Georgios; Kooner, Karta S.; Núñez, Carlos; Schofield, Daniel; Sierra García, Jesús Aníbal (Springer, 2015)
      In this paper we find various new backgrounds in Type IIB, IIA and M-theory with an AdS3-factor. The solutions are smooth and preserve small amounts of SUSY. These new backgrounds are found by application of non-Abelian ...
    • Geometric inflation 

      Arciniega, Gustavo; Bueno, Pablo; Cano, Pablo A.; Edelstein Glaubach, José Daniel; Hennigar, Robie A.; Jaime, Luisa G. (Elsevier, 2020-01-22)
      We argue that the presence of an inflationary epoch is a natural, almost unavoidable, consequence of the existence of a sensible action involving an infinite tower of higher-curvature corrections to the Einstein-Hilbert ...
    • On AdS to dS transitions in higher-curvature gravity 

      Otero Camaño, Xián; Edelstein Glaubach, José Daniel; Gomberoff, Andrés; Sierra García, Jesús Aníbal (Springer, 2015)
      We study the possible existence of gravitational phase transitions from AdS to dS geometries in the context of higher-curvature gravities. We use Lanczos-Gauss-Bonnet (LGB) theory with a positive cosmological constant ...
    • T-duality and high-derivative gravity theories: the BTZ black hole/string paradigm 

      Edelstein Glaubach, José Daniel; Sfetsos, Konstantinos; Sierra García, Jesús Aníbal; Vilar López, Alejandro (Springer, 2018)
      We show that the temperature and entropy of a BTZ black hole are invariant under T-duality to next to leading order in M ⋆− 2, M⋆ being the scale suppressing higher-curvature/derivative terms in the Lagrangian. We work in ...
    • T-duality equivalences beyond string theory 

      Edelstein Glaubach, José Daniel; Sfetsos, Konstantinos; Sierra García, Jesús Aníbal; Vilar López, Alejandro (Springer, 2019-05-16)
      We examine a two parameter family of gravitational actions which contains higher-derivative terms. These are such that the entire action is invariant under corrected T-duality rules, which we derive explicitly. Generically ...
    • Towards geometric inflation: The cubic case 

      Arciniega, Gustavo; Edelstein Glaubach, José Daniel; Jaime, Luisa G. (Elsevier, 2020)
      We present an up to cubic curvature correction to General Relativity with the following features: (i) its vacuum spectrum solely consists of a graviton, (ii) it possesses well-behaved black hole solutions which coincide ...
